Most people with Heads/cam or 383 LT1's get 30-36 lb injectors. What you need to do is scan your car and see what your injector duty cycle is. If it is high then you need to get new injectors. 30lb SVO injectors will work great.

Due exactly as the guys above said and you will be in perfect shape. I went with SVO 30lbs on mine and they seem to give all the fuel she needs.

I disagree, stock 24Lbs are good for a while, there was a blown LT1 making 790rwhp, he was still on 24lbs, later upgarded, I would upgrade the fuel pump and thats about it.
